What are the benefits of having a 600Mbs cable on a 150Mbs hard disk device.

It has been said to me that the connector for the hard disk would be better having a cable capable of communicating at 600 Mb/s on a hard disk that reads from the disk at 150 Mb/s why ?

  1. if it is a sata III device then use a sataIII cable, else there may be drop-outs etc. you won't see a speed issue, but you might stop the once in a year bad write or read.

    First of all, all SATA cables are all the same as regards their speed capability, regardless of what it says in the product advertisements. It's just a 'con' by the cable manufacturer so they can charge you more for the "faster" cables.

    So the cable you use is irrelevant. The only difference between SATA cables is their quality, not their speed ability. So fitting a different cable will make no difference to the transfer speed per se, though a better quality cable may well perform better than a cheap quality one.

    What does make a difference is the specification of the SATA controller on your motherboard (SATA I, SATA II or SATA III), and the SATA specification of the attached hard drive. The lower of the two determines the maximum transfer speed that can be achieved.

    Ok so would there feasibly be an advantage anywhere of putting a SATA 3 cable between for argument sake a SATA I hard-drive and Motherboard connection ?
  4. no. no advantage

    I thought I'd already made that clear. In reality, there is no such thing as a "SATA III" cable even if it's advertised as such. They are all just SATA cables, the cables themselves do not have a speed specification. it's just a 'con' by the manufacturer to trick you in to paying more for a supposedly "faster" cable. It's a myth.
